IBM PCs used a cheap hardware implementation, meaning that the voltage output was directly proportional to the numeric code. When combined with the CRT displays of the time, this tended to produce a transfer function with a gamma of 2.2. The early colour capable browsers were mainly on IBM PCs, and mainly used with CRT displays, so the IBM PC plus CRT colour space became the de facto colour space. sRGB is mainly gamma 2.2, but with some tweaking at lower intensities. When specifications got sufficiently formalised that a colour space had to be identified, sRGB was chosen as it was very close to the de facto colour space for most users. -- David Woolley Emails are not formal business letters, whatever businesses may want. RFC1855 says there should be an address here, but, in a world of spam, that is no longer good advice, as archive address hiding may not work.
